As is known to all of the rolling bearing performance depends largely on its material properties.As the world's largest rolling SKF bearing manufacturer SKF bearing usually use low alloy and high purity of whole quenching chrome steel as the material skf bearings supplier http://www.spherical-roller-bearing.net/ ring and rolling body is made of.Using carburizing steel under high impact load and alternating bending stress of SKF bearing.In recent years, because of the SKF bearing steel quality continuously improve (rise in price, of course), to make its SKF bearing capacity increases significantly.Research results and practical experience have proved that today's standard rolling bearings SKF bearing steel manufacturing, in good lubrication, clean environment and under the condition of load is not big, have infinite fatigue strength can be achieved.SKF bearing ring and rolling body heat treatment process to ensure SKF bearing within 150 degree, size stability.For higher working temperature, need to use special heat treatment method.If the SKF bearing used in corrosive environment, the need to SKF bearing steel are corrosive.Made of stainless steel standard SKF bearing in the code to add prefix "S" and the suffix "W203B".The SKF bearing and the overall quenching SKF bearing steel bearing the main size and carrying capacity is the same.In order to maintain its corrosion resistance, in the process of installation and use of the surface cannot be damaged.Silicon nitride balls used in ceramic production SKF bearing spindle.Ceramic ball is much lighter than steel ball, centrifugal force and friction is significantly smaller than steel ball.When the SKF bearing grease lubrication in still can achieve high speed, and long service life, low working temperature.
